Interesting Question on Co-primes
I found this question somewhere online, which went as follows: For each integer x in a given range [L, R], find the count of integers in the given range that are co-prime with x. Constraints: 1 <= L <= R <= 1e5
A brute force solution would fail the time limit, does anyone have an optimal solution?
